Both units were at or near fµll power and eleven circulat~ng pumps were in operation at the time the turtle was found.
The turtle
- was captured during the cleaning of the trash racks.
The specimen was in good shape (alive) when recovered.
Its' carapace length (SL) and width (SW) were 23 and 22 centimeters, respectively, and it weighed approximately 2.2 kilograms..
All three turtles were turned over to R. Schoelkopf.of the Marine Mammal Standing Center (MMSC), of Brigantine, New Jersey.
The MMSC held the live specimens for several days.
The specimen collected on September 24, 1987 died on October 2 and the specimen collected on September 29, 1987 was scheduled to be transported to Florida for release.
Both dead specimens were disposed of by MMSC near Brigantine, New Jersey.
The Senior Shift Supervisor was initially notified of the occur-rences of the turtles by the on-duty intake operator.
Agencies notified after each occurrence includ~d:
U.S. Nuclear Regulatory Commission U.S. National Marine Fisheries Service New Jersey Department of Environmental Protection Delaware Department of Natural Resources*and Environmental Control APPARENT CAUSE OF OCCURRENCES Sea turtles are a summer migrant, c.ommon to Delaware Bay.
Small numbers typically occur in the lower Delaware Ri~ver near Salem during July through September.
Past experience indicates.that healthy sea turtles are usually able to avoid the approach velocity of the CWS intake, although occasionally one will bedome entrapped in the area of the trash bars.
Some turtle mortalities are also attributed to animals injured by boats or commercial fishing operatioris which float into the area of the circulating water intake.
ANALYSIS OF OCCURRENCE The CWS intake is mon.i.tored for the accumulation of debris, which is periodically removed.
Any turtles which are observed in the area of the trash bars are recovered immediately.
Between 1979 and present, a total of 28 sea turtles have been collected at or in the immediate.vicinity of the plant.
Of these, nine (32 percent) were Kemp's ridleys and 19 (68 percent) were logger-heads.
Of the total turtles collected, 9 (32 percent) were alive when recovered~
CORRECTIVE ACTION The trash bars are observed at least a.nee. per 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> shift and cleaned at least once per day.
Any sea turtle observed on the trash bars is removed immediately.
Resuscitation will be attempted if the turtle is not unquestionable dead.
In accordance with standard procedure, all specimens will be held under appropriate conditions and turned over to the Marine Mammal Standing Center.
